Application filed June 28, 1964. Serial No. 214,661.

To all wit/rm it may; concern:

Be it known that l, Gnono Lnenn, engineer, a subject of the Emperor ofAustria'Hungary, and c resident of No. 34 vveimarerstrnssc,

Cir ottenhurg, in the Empireof Germanvq nvented certain new and usefullmprovei ments in lvleans for Indicating the Loaded in iition ofFirearms, (for Which'Lctters nt of Greet Britain, No. 13,1457, of June10, 550%, have been granted to me,) ofwhich the following is an exact,full, and clear descri pti on.

Tlhis invention relates to means whereby it will be readily indicated onthe exterior of "resins whether or not a cartridge iscontsined n thecartridge-chamber of the barrel. The era back or" not being able to seeon the out- .ide of the ordinary military firearms the coded conditionof the some is very annoying, especisllyin connection withfirearmshavingn automatic loading device as, forinstonce, c known recoil-loadinglirearmshecause hey are regularly reloaded after every dishnrge, andtherefore in the event of carecert-ridge is inserted in thecartridge-chem her--71. 5., when closing the breech-the certridgewill'strike against the wedge-surfaces and the lovers or members will benntomnt icnlly thrown outwnrd, in consequence of which sufficiently longor wide and very conspicuous ports on the on'tsid'e'of the will indicatethe loaded condition the latter. it is essential that the part extendinginto the ccrtrilge chnmber be formed with 'a wedge-,- sheped surfaceendbear laterally upon the outer surface or rim of the cartridge,relieve--- by the requisite projection can be obtained forindicnting theloaded condition of the firearm. The invention is preferably carried outin such e, manner that the indicating-levers may also. servecartridge-extractors.

The object of the invention is to prodncc a very striking indication ofthe loaded condition of the firearm, and it can also be fulfilled bylever mechanism, by means of which a small indicating movement of themembers which are actuated during the insertion of the l cartridgeproduces an increased movemcntof l the special indicating part.

I In the accompanying drawings, Figures 1 i and 2 are longitudinalsections through the i Fig. 2. 3 and 4' show the indicatingleveremployed as an extractor. Figs. 5 and l. 6 show in side elevation thepositions of the parts shown in Figs. 3. and t. Fig.7 is a modification.The indicating means, for which. is used a' lover or equivalentmember-such as a pawl, a. slide, and the like with an indicatingpriojec'tion--may be located on the receiver or on the movable breechpart or breech-bolt.

According to the construction shown in Figs. 1 and 2 theindicating-leverismounted in aslot of the fixed receiver w behind the barrel orcartridge-chamber b. This lever is fulcrumed at c and at'its front endhas a. wedge-shaped projection k1, movable laterally in e. recess in thereceiving end of the barrel, where it bears against the casing or rim ofthe cartridge when 2. cartridge is'contained in the chamber. By meansoj-the spring-f the lever 2f tends to more inward. If no cartridge is inthe chamber. the projection lt'occupics the position shown in Fig. 1,and when in this position the back or projectionjof the lever is loweredflush with the receiver 1 but as soon as e. cartridge is inserted in thechambcrb the lever z'must, in consequence of the engngementof thecartridge with the wedge-shaped projection k, move outward against thenotion of the spring and finally as sume such position that the back orprojection j protrudes from; the receiver, Fig. 2. Consequently thisserves as a. true indication that e. cartridge is contained in thecartridgechnmber, the rim of the cartridge forming the support for theend of the lever. The projection /r is fiat at its inner end and onitsrear face is inclined to permit the free insertion of thecsrtridge.The indicating-lever may be mounted on a movable breech part or thebreeeh-bolt, inwhich event the inclined surface of the dependingprojection must be at the front instead oihat the rear, whereby inconsequence of the lever impinging against the cartridge when thebreech-bolt moves forward the outward movement of the lever occursduring the closing of the breech. This construction is shown in Figs. 3to 6. .Inthie hrrangoment the lever is subjected to the action of thespring c, so as to oscillate inwardly:
